T 0 all 'whom it mag/'concern Be it'known that I, FREDERICK A. SoHossow, citizen of the United States, residing at Detroit, county o-f Wayne, State of Michiganbhave invented a certain new and useful Improvement inl Flush-Valves, and declare the following to be a full, clear, and exact description kof the same, such as will enable others skilled inthe' art to which Ait pertains to make and use the same, reference being hadr to the accompanying drawings, which form a part Aof lthis specification.

My invention relates to a flush valve shown in the accompanying drawing and more particularly pointed out in the following specification and claims.-

One of the objects of my invention is to provide a device simple and inexpensive in itsconstruction and operation capable of effecting a thorough flushing of a closet' bowl or other appliance by maintaining the valve continuously open when raised until the water has been discharged from the tank controlled bythe valve. This result being obtainedby the water in passing from the tank acting upon means provided to maintain the valve in its vopen position until the water is discharged whereuponthe valve automatically seats itself that the tank may again be refilled.

Another object of the invention is to provide means to insurewhat is known as an afteriill following the discharge of the water through the closet bowl, whereby the water seal required in the closet bowl may be maintained. i

Other advantages and improvements will hereafter appear. t I

In the drawings accompanying this specificationigu're l, isda longitudinalvertical section through a flushing tank indicating in elevation the flush valve casing and means for manually-raising the`valve. v Fig. 2, is a vertical sectional view through the valve casing with'parts broken away, sho-wing the valve seated. Fig;l 3,*is a similar view showing the valve raised. Fig. 4, is a detail view in section of a modification showing in lieu of the valve controlling disk, a cup having a small perforation in its lower wall.

Referring now to the letters of reference placed upon the drawings :-A, denotes a flushing tank or water reservoir.

B, indicates a casing provided with an outlet pipe B, projecting through the walll of the tank and threaded to receive the `usual pipe connections .(not shown) leading to a closet Ybow-l or other place of delivery.

carried on the' end "of therod'I; A1. a

Y m', is a relatively small perforationin they bottom of the cup to slowly release the water contained within the cup.

Having indicated the several parts by reference letters the construction and operation of the device will be readily understoodz-To Hush the closet the valve C is manually raised by pulling down the handle K controlling the action of the bell crank levers. Upon raising the valve C,

the disk I carried by the rod I,is lowered into the ypath of the water passing from the tank which bearing thereon serves to' maintain the valve in its elevated position until the water is discharged from the tank,

Awhereupon the valve automatically seats itself, being guided toits seat Vby the guide D. The tank may then be refilled in the usual manner.

In order to provide; for the after lill required. to maintain a water seal in the closet bowl, I have indicated in the -modilication shown in Fig. t, a cup provided with a small. perforation to discharge water. This cup is designed to take the place of the diskI to'maintain the valve C in its open position while water is heilig discharged from the tank and for a brief period thereafter, governed by the time required for the water contained in the cupv to lpass therefrom, whereupon the weight of the valve C,

overcoming -the weight of the empty cup automatically returns to its seat.

Having thus described Ymy invention I what I claim is,:-

l. In a device of the character described,

a casing having an inlet port and a discharge port', an over-flow pipe` connectedwith the casing, a supporting member secured to the upper end of the overflow pipe; a valve controlling the inlet port, a bell crank lever pivoted onv said supporting member, means adapted to limit the tilting action of the lever, a link connecting one'arm of the lever' with the valve, a rod connected with the other arm of the bell crank lever andv suspended within the over-flow pipe, means carried by the rod adapted to be lowered by the lever into the path of the water passing through thecasing said means when acted upon by the water being adapted to maintain the valve in its open position until the water is discharged, and means for actuating the lever.

2. In a device of the character described,

acasing yhaving an -inlet port and a dis- Y charge port, an over-flow pipe connected with .the casing, a supporting member secured to the upper end of the overflow pipe, an upright on lthe supporting member, a

valve controlling the inlet port, abell crank f lever pivoted on the upright of said support- .ing member, the bell crank leverliaving a Copies of this patent may be `o'ntainedfor projection, an adjustable stop mounted on the proJection of the bell crank lever for engagement with said upright to limit the tilting action of the bell crank lever, a link connecting one arm ofthe lever ywith the valve, a rod connected with the other arm of the lever and suspended within the overflow pipe, means carriedV by said rod adapt- .K ed to be lowered by the lever into the path of the water passing through the casing,

said means when actedl upon by the water being adapted to maintain the valve in'its open position until the water is discharged, and means for actuating the lever.

3. In a device ofthe character described,

`a casing having an inlet port'and a discharge port, a valve controlling the passage through the inlet port, a lever to raise the valve, a perforated cup connected-with the lever adapted to be vlled with water. and to be acted upon by the water passingthrough the casing so as to maintain the valve in its elevated position during the discharge of the main body ofV water through the casing and for a brief period thereafter, and thereby moving slowly automaticallyY to valve closingv position so that a relatively small volume of water may' subsequently pass through the casing `to provide an after-lill.

Il. In a device of the character described, a casing having an inlet portsin its upper side at one end thereof and an outlet port in.

its bottom at the opposite end thereof, the sidewalls of said casing being imperforate,

a valve controlling the passage through thev inlet port,means to raise the valve, means suspended from the aforesaid means in alinement'w-ith the outlet vport andmovable ve cents each, by addressing the (lomniissioner"tof` Patents, Washington, D. C. 1
